[Mapserver-users] dynamic point generation with php-mapscript

[Paul Dymecki]

Hi Eric,
     Sorry for a possibly dense question, but here goes, Can the same script
be used by generateing the points from a db link and not requerying on each
map_query?  I'm thinkin probably not but just thought i'd check?
thx,
Paul

query the database for your points, create new point objects using
ms_newPointObj(), set the XY coordinates, and draw the point on the layer.
If you want some specific code examples, I can send along snippet.
